Introduction

This document is the result of a joint industry project, established to develop a recommended practice (RP) covering design, manufacturing, maintenance and operational aspects associated with lifting appliances intended for subsea lifting operations.

Present rules, regulations and standards for offshore lifting appliances are based mainly on risks associated with cranes of moderate capacity and lifting operations to/from supply vessels. Subsea lifting is complex - it involves technology, working procedures, weather evaluations, competence, organisations and management. Challenges related to modern subsea lifting operations, involving for example higher lifting capacities, greater water depths and incorporating motion compensation systems, are covered to a lesser degree in the present codes.

It is therefore the ambition that this document shall increase the overall awareness of risks from subsea lifting activities and how to best manage these risks.
